The proper spelling of the medical term "nervus cutaneus brachii lateralis" can be tricky, but using the International Phonetic Alphabet (IPA) can help clarify its pronunciation. The word is composed of Latin roots and indicates a nerve that runs along the lateral side of the brachial arm and innervates the skin. Phonetic transcription can assist in breaking down the word into easily pronounced segments, such as /ˈnɜrvəs kjuːˈteɪniəs ˈbreɪkiː aɪ ˌlætərˈælɪs/. By mastering phonetics, one can more confidently and accurately communicate complex medical terminology.
The nervus cutaneus brachii lateralis refers to one of the peripheral nerves in the human body. It arises from the brachial plexus – a network of nerves that originate from the spinal cord in the lower neck and upper back. Specifically, the nervus cutaneus brachii lateralis branches off from the lateral cord of the brachial plexus.
This nerve is responsible for innervating the skin on the lateral aspect of the upper arm. It provides sensory function, allowing for the perception of touch, temperature, and pain on the outer part of the arm. Additionally, the nervus cutaneus brachii lateralis plays a crucial role in transmitting sensory information related to proprioception, which is the awareness of the position and movements of the arm in space.
Damage or injury to the nervus cutaneus brachii lateralis can result in a loss of sensation or altered sensory perception in the affected area. This can lead to difficulties in accurately perceiving touch or temperature changes and may impact motor function, such as the ability to perform precise movements with the arm.
Understanding the anatomical location and function of the nervus cutaneus brachii lateralis is essential for healthcare professionals, particularly in the fields of neurology, orthopedics, and rehabilitation.
Lateral brachial cutaneous nerve, a sensory branch of the axillary supplying the skin over the lower portion of the deltoid and for a distance below its insertion.
